Wait, can a disaster recovery instance even be modified like that?

I think the backup task could also be a reason.

Hmm, the legal and regulatory environment seems like a pretty important factor to me. I'm not sure why that wouldn't be considered.

This seems like a tricky one. I'll need to think through the relationship between totalKeysExamined and totalDocsExamined to figure out the right answer.

Hmm, I'm not sure. The variable volume and material cost sensitivity in option C also seems like it could gain a lot from EDI. Automating the purchasing process could help manage those fluctuations.
